Park tool site can help you with the tool you need for your particular crank. The Park ccp-22 is for square taper cranks. But better yet is that Park sells a tool called the Universal Crank Puller that works for both square tape and splined cranks and it works by attaching the tool to the bolt then an adjustable wrench or the right size box wrench to the tool then use; this way you'll have one tool for both style of cranks. http://www.parktool.com/product/univ...d-cranks-cwp-7
